The idea is a skyproc that scan all armor installed in you game and add to all that armors a new requirement, that is a Blueprint and spread that blueprints over leveled list and merchants. The Blueprint is removed like any other material after create the item.
One of the worst issues from Skyrim smith system is how easy is farm XP using the forge, and there is many mods that add new items to forge that just not make sense in materiais, exploiting the game. With that limitation, forge items will be much more harder and rewarding and better yet when using mods like Loot and Degradation, making upgrade items much more important.
